I need a NIC that can listen to broadcasting on multiple VLAN's.

Do I simply need a card that can support 802.11q like:

http://secure.newegg.com/Shopping/ShoppingCart.aspx?Submit=view

This card will need to be installed in a PC that will be connected to a Cisco Catalyst 2960 that is trunked to other catalysts.

So for example, if we have VLAN's 400-410 and 500-510 and I need it to listen to broadcasts on 402-410 and 502-510 how would I set this up exactly? Do I need to create a trunk between the PC and the switch? Do I need any special software on the PC to do this?

if we are talking about 802.1q,
then you need ordinal nic (vlan capable) and wireshark.
if a port under that NIC is configured as trunk with multiple vlans, then you should receive broadcast traffic from all vlans.

software - wireshark

Sorry, yes 802.1q

Is that nic above an ordinal nic (or can you point me to one)?

Is the configuration done within a piece of software for the nic, or per wireshark?
